uieoturer. a subject of the Grand or residing at 48 Holzgsrtenstrssse,iPfo-" heirn, German Empire, invented R6. and useful Improvements inProcesses and Apparatus for Manufacturing Lined Metellie Hose, of whichthe following is specification.

My invention relates to 9. process of end o. psintus for manufacturingspiral metallic e "loving an inner lin-i-ng-hose of india-rt1bothersuitable material. 1e novel feature of the invention is that thelining-hose is fed through the hollow spindle of the metallichose-making machine during the manufacture of the metallic hose in suchmanner the finished hose complete with the lining can be drawn from thespindle. Prior to entering the hollow windingspindle the liningdiosc ispressed or folded together in the direction of its length, and sfterremoval of the linished hose the lininghose is again distended byconducting sir, liquid, or other suitable agent into it, so that theouter wall of the lininghose lies tightly against the inner Wall of theouter metallic hose.

One form of construction of a machine for carrying out the new processis illustrated in the accompanying drawings, in which- Figure 1 is a.side elevation of the machine; Fig. 2, longitudinal section through theheed of the winding-spindle with device for pressing in the lining-hose.Figs. 3 and 4 are cross and longitudinal sections of a piece of metallichose with collapsed lining. Figs. 5 and 6 are like views of the metallichose after distention of the lining, Figs. 2 to 6 being drawn to anenlarged scale.

The hose-winding machine is mounted on e. suitable framing and furnishedwith a hollow spindle (1 upon which the hose 7) is wound in wclldinownmanner. The lining-hose of rubhcr or other suitshle material to heintroduced into the metallic hose is wound on the reel in. At theopposite end oi t iemschine is :i reel 0, to which the piece of finishedmetallic hose connected. This reel c turns on the pin (Z and is hold bythe ironic f, which rotates on the axis 51 g, located at right angles tothe pin (Z. Similarly the reel in turns on so. axis located at rightsnglcis to the pin on e known that l, EMIL Wnzmnusnni ich it is mounted,the said axis. like the spindle c. When a llkliitlllc hose is to herovided w h rubher or otlierlininz hose I j p i. 1 the latte is redrroni the reel in through tne hollow winding-spindle to the reel 0. lnorder to'enshle this to be done, the rubber hose 1 before entering: thespindle n1 is pressed in or tolded together. l 'or this purpose thereunity, for instance, be a roller 7) located in a recessed part ol theheed 0, which roller presses in the hose unwinding troin the reel m,Fig. 3, or the hose may be drawn from the reel m in already-foldedcondition. After the lining-hose has been iniisted it will lie tightlyagainst the inner well of the outer metallic hose and forms, as it were,an integrsl port of it. The metallic hose is wound on the spindle o in Yll-known manner. Each time the spindle (1 .:is been wound the hose isautomatically or by hand pushed oi! the spindle and with the liningwound onto the reel 0.

The details of the apparatus may he varied in numerous ways. Thisapplies in pan ticuler to the description of windingunschine employed.The essential feature of the invention is that the lining-hose is fed tothe metallic hose during the course of msnui'scture of the letter and ispressed in or folded together in longitudinal direction prior to itsentering the hollow winding-spindle.

Having thus dcscrilwd my iin'ci'ition, what I claim as new, and desireto scrurc by linttcrs l utcnt i 1. The process o'l lllzll'lll inc urinelined spirsi metallic hose, consisting in winding rue-- l swindle, andsimultm e on u uolio conduct hose from the inn suhstnntislly asdescribed.

' 1;. ni nu'l seluiing lined spin winding inclatter, and then distendingthe lining-hose, by means of asuitable agentuntil it lies tightlyagainst the inner Wallof the metallic ,hose, substantially as described;

,3. In apparatus for manufacturing lined spiral metallic hose, a hollowspindle, a lining-hose reel mounted at the head thereof and at rightangles to the spindle-axis, and means for rotating the reel and spindle,substantially as described.

4. In apparatus for manufacturing lined spiral metallic hose, a hollow sindle a lining-hose reel' mounted at the ead thereof and at right anglesto the spindle-axis, a roller mounted between the reel and the spindle,for making a longitudinal fold in the lin-v ing-hose, on its enteringthe spindle, and
